MLK-17815-2 ata: imx: imx8qm: configure phy impedance ratio
- To save power consumption, PHY related CLKs can be
gated off after the configurations are done.
- The impedance ratio should be configured refer to
differnet REXT values.
0x6c <--> REXT valuse is 85Ohms
Default values 0x80 <--> REXT value is 100Ohms.
- IMX8QM_HSIO_PHY_X1_APB_CLK is mandatory required when
access SATA PHY registers. Change the power domain to SATA.
